  1. 21. How to measure the true end-user impact of Energy Performance features in a mobile network

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Diba Rezaie; [2023]
    Nyckelord :lte; 4g; qos; qoe; quality of experience; quality of service; measure; end-user; communication; mobile network; mobile operator;

    Sammanfattning : The Information and Communication Technology (ICT) industry is one of the most energy consuming industries in the world. With the increase of the number of global mobile traffic users which is growing rapidly for each year, it is more important than ever for all industries to implement energy efficient methods to decrease the greenhouse gas emissions.

  3. 22. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  4. 23. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Björn Jarfors; [2023]
    Nyckelord :Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Sammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER

  5. 24. Påföljder av inbyggd fukt i konstruktionselement av korslimmat trä

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Nils Albertsson; Isak Gustavsson; [2023]
    Nyckelord :Cross-laminated timber; moisture; timber floor construction; moisture diffusion; Korslimmat trä; Fukt; Träbjälklag; Fuktdiffusion;

    Sammanfattning : In spring 2023, two engineering students from Jönköping University collaborated with GBJ Bygg Jönköping to investigate the impact of moisture on cross-laminated timber (CLT) and its drying process. The study aimed to identify potential issues, damages, and propose mitigation methods. LÄS MER

  7. 25. Adapting Household Energy Consumption: How Consumers in Germany and Sweden Managed the European Energy Crisis

    Master-uppsats, Lunds universitet/Institutionen för tjänstevetenskap

    Författare :Emmelina Eriksson; Daniel Götting; [2023]
    Nyckelord :Sustainable consumption; Energy consumption; Energy crisis; Social practice theory; disruptions to practices; Social Sciences;

    Sammanfattning : Residential energy consumption in Europe is unsustainable, relying heavily on fossil fuels and contributing to climate change. The European energy crisis, as a naturally occurring experiment, disrupted energy consumption in households due to drastically increased prices and raised public awareness while creating a unique opportunity to study the dynamics of change in household energy consumption.
